A unilateral frontal sinusotomy is a surgical procedure that involves accessing the frontal sinus through a transorbital approach, which means the surgery is performed through the orbit of the eye. This procedure is specifically indicated for the removal of a mucocele, osteoma, or other mass lesions that may be present in the frontal sinus. The term "Lynch-type procedure" refers to the specific technique used in this surgery, which is characterized by a precise incision made just below the eyebrow on the side of the affected sinus. This approach allows for direct access to the frontal sinus while minimizing damage to surrounding tissues. The procedure involves several critical steps, including the elevation of soft tissues, the use of specialized instruments to cut through the bone, and the careful removal of the lesion. After the lesion is excised, the bone flap is replaced and secured, followed by layered closure of the soft tissues and skin. This detailed approach ensures that the underlying structures are preserved as much as possible while effectively addressing the pathological condition within the frontal sinus.

The unilateral frontal sinusotomy via a transorbital approach is performed for specific conditions affecting the frontal sinus. The primary indications for this procedure include:
The procedure for a unilateral frontal sinusotomy via a transorbital approach involves several critical steps, each designed to ensure effective access and removal of the lesion while minimizing trauma to surrounding structures.
Post-procedure care following a unilateral frontal sinusotomy includes monitoring for any signs of complications such as infection or bleeding. Patients may experience swelling and discomfort in the area, which can be managed with appropriate pain relief measures. Follow-up appointments are essential to assess healing and ensure that there are no residual issues related to the frontal sinus. Patients are typically advised on activity restrictions and signs to watch for that may indicate complications, ensuring a smooth recovery process.

| 50 | Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 51 | Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 52 | Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use). | 62 | Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate. | GC | This service has been performed in part by a resident under the direction of a teaching physician | LT | Left side (used to identify procedures performed on the left side of the body) | RT | Right side (used to identify procedures performed on the right side of the body) |
